[0002] With the continuous development and popularization of electronic devices, electronic devices have also become indispensable entertainment tools and social tools in people's daily lives, and people's requirements for electronic devices are getting higher and higher. Taking mobile phones as an example, in order to obtain a higher screen-to-body ratio, the photosensitive module of the electronic device is generally set under the display screen to receive light passing through the display screen to realize the corresponding function. At present, the common under-screen photosensitive scheme is generally to open holes in the laminated structure of the display screen to increase the light transmittance of the display screen. However, opening holes in the laminated structure of the display screen will expose part of the metal layer of the display screen (such as the cathode layer), thereby increasing the light reflectivity of the opening area of ​​the display screen, resulting in differences in visual effects between the opening area of ​​the display screen and other normal areas.

[0017] The present application is further described in detail below in conjunction with the accompanying drawings and examples. It is particularly noted that the following examples are only used to illustrate the present application, but are not intended to limit the scope of the present application. Similarly, the following examples are only some embodiments of the present application rather than all embodiments, and all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application.

[0018] Reference to "embodiments" in this application means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0019] See also Figure 1 to Figure 2 , Figure 1 is a schematic diagram of the structure of an electronic device 10 provided in an embodiment of the present application, Figure 2 yes Figure 1 FIG. 1 is a schematic diagram of an exploded structure of an electronic device 10 .

[0020] The electronic device 10 provided in the embodiment of the present application may be a device with a display function such as a mobile phone, a tablet computer, an e-book reader, and a smart watch. The following is an example in which the electronic device 10 is a mobile phone. Figure 1 to Figure 2 As shown, the electronic device 10 may include: a housing 100, a display panel 200 and a photosensitive module 300. Among them, the housing 100 can be used to install the functional devices required by the electronic device 10, and the housing 100 is also connected to the display panel 200, and can be enclosed together with the display panel 200 to form a receiving space 400. The photosensitive module 300 can be arranged in the receiving space 400 and arranged opposite to the display panel 200, and the photosensitive module 300 can receive external light emitted from the display panel 200 into the receiving space 400 to achieve functions such as fingerprint recognition or ambient light detection. In this embodiment, the display panel 200 can have a high light transmittance and a large field of view angle on the side facing the photosensitive module 300, so that the photosensitive module 300 can receive a wider range of light to improve the light sensing accuracy and sensitivity of the photosensitive module 300.

[0021] Exemplarily, the housing 100 may include: a middle frame 110 and a rear shell 120. Among them, the display panel 200 may be covered on one side of the middle frame 110, the rear shell 120 may be covered on the other opposite side of the middle frame 110, and the display panel 200 may be enclosed together with the middle frame 110 to form the aforementioned accommodation space 400. At the same time, the middle frame 110 may be used to carry the functional devices required by the electronic device 10, such as circuit boards, batteries, speakers, microphones, etc., and the rear shell 120 may be used to protect the functional devices set on the middle frame 110. In addition, since the middle frame 110 and the rear shell 120 are generally directly exposed to the external environment, the middle frame 110 and the rear shell 120 may have certain wear-resistant, corrosion-resistant and scratch-resistant properties, or a layer of wear-resistant, corrosion-resistant and scratch-resistant functional material may be coated on the outer surface of the middle frame 110 and the rear shell 120 (that is, the outer surface of the electronic device 10).

[0022] It is understandable that the specific structure of the aforementioned housing 100 is only an exemplary description, and the housing 100 may not be limited to being generally configured as in the aforementioned embodiment. For example, the housing 100 may also include only the rear housing 120, and the edge area of ​​the rear housing 120 may extend in its thickness direction, so that the rear housing 120 may form an open structure, and the display panel 200 may be directly covered at the opening of the rear housing 120, and together with the rear housing 120, enclose the aforementioned accommodation space 400. Of course, there may be a variety of designs for the housing 100, which are not described in detail in this embodiment.

[0023] All directional indications (such as up, down, left, right, front, back...) in the embodiments of the present application are only used to explain the relative positional relationship, movement, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication also changes accordingly. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally also includes steps or units that are not listed, or optionally also includes other steps or units inherent to these processes, methods, products or devices.

[0024] See also Figures 3 to 6 , Figure 3 yes Figure 2 The structural diagram of the display panel 200 is shown in FIG. Figure 4 yes Figure 3 A partial cross-sectional structural diagram of the first display area 201 along V-V, Figure 5 yes Figure 4 A partial enlarged schematic diagram of point A in the middle. Figure 6 yes Figure 4 A local enlarged schematic diagram of point B in the middle.

[0025] The display panel 200 may be an OLED (Organic Light-Emitting Diode) panel, and the display panel 200 may be a flexible panel or a rigid panel. Figure 3 As shown, the display panel 200 may include: a first display area 201 and a second display area 202. The first display area 201 may be arranged opposite to the photosensitive module 300, and the photosensitive module 300 may receive light emitted from the first display area 201 into the accommodating space 400. At the same time, the light transmittance of the first display area 201 is greater than the light transmittance of the second display area 202, and the viewing angle of the first display area 201 facing the photosensitive module 300 is also greater than the viewing angle of the second display area 202 facing the rear shell 120. The second display area 202 is connected to the first display area 201 and is arranged around the first display area 201. In this embodiment, since the first display area 201 has a higher light transmittance and a larger viewing angle than the second display area 202, the photosensitive module 300 can receive a wider range of light to improve the light sensing accuracy and sensitivity of the photosensitive module 300.

[0026] Optionally, the first display area 201 and the second display area 202 may also be divided according to design requirements. That is, the second display area 202 may not be limited to being connected to the first display area 201 and being arranged around the first display area 201, and this embodiment does not limit this. In addition, in some embodiments, the design of the second display area 202 may also be omitted, that is, the first display area 201 may be the complete display area of ​​the display panel 200, so that the entire display area of ​​the display panel 200 has a higher light transmittance and a larger field of view, and is not limited to a partial display area of ​​the display panel 200.

[0027] The terms "first", "second", and "third" in this application are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first", "second", and "third" may explicitly or implicitly include at least one of the features.

[0028] Exemplarily, the display panel 200 may include: a color filter layer 210 and a pixel light emitting layer 220. Figure 4 As shown, the color filter layer 210 and the pixel light emitting layer 220 are stacked, and the pixel light emitting layer 220 can emit light to pass through the color filter layer 210 to the outside of the display panel 200, and the color filter layer 210 can filter the light emitted by the pixel light emitting layer 220 so that the light of the corresponding color can be transmitted to the outside of the display panel 200, so as to realize the image display function of the display panel 200. At the same time, the color filter layer 210 and the pixel light emitting layer 220 in the first display area 201 can also be respectively provided with a first light-transmitting hole 211 and a second light-transmitting hole 221, and the first light-transmitting hole 211 and the second light-transmitting hole 221 can also be coaxially arranged. In addition, the first light-transmitting hole 211 and the second light-transmitting hole 221 are respectively provided with a first refractive film 230 and a second refractive film 240, and the external light can pass through the first refractive film 230 and the second refractive film 240 in sequence to enter the accommodating space 400 and be received by the photosensitive module 300. In this embodiment, the first refractive film 230 can be used to converge the light emitted from the first light-transmitting hole 211 into the second light-transmitting hole 221 to improve the light transmittance of the first display area 201, and the second refractive film 240 can be used to diffuse the light emitted from the second light-transmitting hole 221 into the accommodating space 400 to expand the field of view of the first display area 201 toward the side of the photosensitive module 300, so that the photosensitive module 300 can receive a larger range of light to improve the light sensing accuracy and sensitivity of the photosensitive module 300.

[0029] like Figures 4 to 5As shown, the color filter layer 210 may specifically include: a black matrix 212 and a filter 213. Among them, the black matrix 212 is stacked with the pixel light-emitting layer 220 and has a plurality of pixel holes 2121, and the pixel holes 2121 can penetrate the black matrix 212 on opposite sides close to and away from the pixel light-emitting layer 220. The filter 213 is arranged in the same layer as the black matrix 212 and is located in the plurality of pixel holes 2121, that is, the plurality of pixel holes 2121 are each provided with a filter 213, and the filter 213 can be used to filter the light emitted by the pixel light-emitting layer 220, so that the light of the corresponding color can pass through the filter 213 to the outside of the display panel 200. In this embodiment, the black matrix 212 is provided with a plurality of the aforementioned first light-transmitting holes 211, and the first light-transmitting holes 211 can also penetrate the black matrix 212 on opposite sides close to and away from the pixel light-emitting layer 220 to ensure that external light can pass through the black matrix 212 to the second light-transmitting holes 221. In the description of the present application, “plurality” means at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0030] Optionally, the material of the black matrix 212 may be a positive resin, and under the influence of the positive resin characteristics, when the black matrix 212 is exposed and developed to form the first light-transmitting hole 211, the aperture of the first light-transmitting hole 211 in the direction of the black matrix 212 close to the pixel light-emitting layer 220 may be gradually reduced, so that the first light-transmitting hole 211 may be arranged in an inverted trapezoidal hole. In this way, the first light-transmitting hole 211 may be formed with a larger opening on the side of the black matrix 212 away from the pixel light-emitting layer 220, so that more light can be injected into the first light-transmitting hole 211 from the side of the black matrix 212 away from the pixel light-emitting layer 220, and is converged by the first refractive film 230 and transmitted to the second light-transmitting hole 221, thereby facilitating the increase of the light transmittance of the first display area 201. Of course, according to different design requirements, the material of the black matrix 212 may not be limited to the positive resin, and the first light-transmitting hole 211 may not be limited to an inverted trapezoidal hole. For example, the material of the black matrix 212 may also be a negative-type resin, and the first light-transmitting hole 211 may also be a rectangular hole or an elliptical hole, which is not limited in this embodiment.

[0031] The first refractive film 230 is disposed in the first light-transmitting hole 211, and the first refractive film 230 can be used to converge the light incident from the first light-transmitting hole 211 into the second light-transmitting hole 221, and partially collimate the light, so as to improve the light transmittance of the first display area 201. Figure 5 As shown, the shape of the first refractive film 230 can match the first light-transmitting hole 211, that is, the cross section of the first refractive film 230 can also be set in an inverted trapezoidal shape. At the same time, in order to enhance the light convergence effect, the refractive index of the first refractive film 230 in the direction of the black matrix 212 close to the pixel light-emitting layer 220 can be gradually increased, so that the light ( Figure 5When passing through the first refractive film 230, the light (indicated by the dotted line L with arrows in the middle) can gradually converge toward the axial center of the first light-transmitting hole 211, and enter the second light-transmitting hole 221 in a direction almost parallel to the axial direction of the first light-transmitting hole 211, so as to reduce the loss of oblique light, thereby improving the light transmittance of the first display area 201. In this embodiment, the thickness of the first refractive film 230 can be 100nm-1000nm, specifically 100nm, 400nm, 500nm, 800nm ​​or 1000nm.

[0032] Optionally, the refractive index of the first refractive film 230 can be linearly increasing or nonlinearly increasing. It only needs to increase the refractive index of the first refractive film 230 in the direction of the black matrix 212 close to the pixel light-emitting layer 220 so that the light can converge to the axial center of the first light-transmitting hole 211. This embodiment is not limited to this.

[0033] Exemplarily, the first refractive film 230 may have multiple first refractive layers 231, and the multiple first refractive layers 231 may be stacked sequentially in the direction where the black matrix 212 is close to the pixel light emitting layer 220. The refractive index of the multiple first refractive layers 231 in the direction where the black matrix 212 is close to the pixel light emitting layer 220 may gradually increase, so that when the light passes through the multiple first refractive layers 231, it can be refracted by the multiple first refractive layers 231 in sequence, and then gradually converge to the axial center of the first light transmission hole 211. In this embodiment, the material of the first refractive layer 231 may be an organic polymer or inorganic silicon, and the number of the first refractive layers 231 may be 3-6 layers, specifically 3 layers, 4 layers, 5 layers or 6 layers.

[0034] For example, when the material of the first refractive layer 231 is an organic polymer, the multi-layer first refractive layer 231 may be composed of a polymer material having one substituent group and multiple substituent groups. Among them, the refractive index of the first refractive layer 231 composed of the polymer material having multiple substituent groups may be greater than the first refractive layer 231 composed of the polymer part material having one substituent group. That is, the refractive index of the first refractive layer 231 composed of the polymer material with more substituent groups is greater, and the refractive index of the first refractive layer 231 composed of the polymer material with fewer substituent groups is smaller. Based on this, the number of substituent groups in the multi-layer first refractive layer 231 in the direction where the black matrix 212 is close to the pixel light-emitting layer 220 can be gradually increased, so that the refractive index of the multi-layer first refractive layer 231 in the direction where the black matrix 212 is close to the pixel light-emitting layer 220 can be gradually increased. In this embodiment, the number of substituent groups can be controlled by the process temperature, and the higher the process temperature, the more substituent groups in the first refractive layer 231, and vice versa.

[0035] The refractive index of the multi-layer first refractive layer 231 may vary in the range of 1.4 to 1.9. Among them, the refractive index of the top layer far from the pixel light emitting layer 220 in the multi-layer first refractive layer 231 is 1.4, and the refractive index of the bottom layer close to the pixel light emitting layer 220 is 1.9. For example, when the number of the first refractive layer 231 is 6 layers, the refractive indexes of the 6 first refractive layers 231 in the direction close to the pixel light emitting layer 220 are 1.4 (HMDSO), 1.5 (SiNO), 1.6 (SiCN), 1.7 (SiNx), 1.8 (SiNx) and 1.9 (SiNx), and the thickness of the top layer far from the pixel light emitting layer 220 in the 6 first refractive layers 231 is the largest (close to 500nm), while the thickness of the other 5 first refractive layers 231 is relatively thin. With this arrangement, the six first refractive layers 231 can refract almost all light with an incident angle greater than 45° to the axial center of the first light-transmitting hole 211 to reduce the proportion of light entering other areas outside the first light-transmitting hole 211, thereby improving the light transmittance of the first display area 201.

[0036] Optionally, the number of the aforementioned multi-layer first refractive layers 231, the range of refractive index variation, and the selected materials can also be adaptively adjusted according to design requirements. It is only necessary that the refractive index of the multi-layer first refractive layers 231 in the direction close to the pixel light-emitting layer 220 can be gradually increased so that the light entering the first light-transmitting hole 211 can converge toward the axial center of the first light-transmitting hole 211. This embodiment is not limited to this.

[0037] like Figure 4 and Figure 6 As shown, the pixel light-emitting layer 220 may specifically include: a pixel definition layer 222 and a light-emitting layer 223. The pixel definition layer 222 may be stacked with the black matrix 212 and have a plurality of receiving holes 2221, and the receiving holes 2221 may penetrate the pixel definition layer 222 on opposite sides close to and away from the black matrix 212, and be coaxially arranged with the pixel hole 2121. The light-emitting layer 223 is arranged in the same layer as the pixel definition layer 222 and is located in the plurality of receiving holes 2221, that is, the light-emitting layer 223 is arranged in each of the plurality of receiving holes 2221. At the same time, the light-emitting layer 223 is also arranged opposite to the filter 213, and may emit light to pass through the filter 213 to the outside of the display panel 200. In this embodiment, the pixel definition layer 222 is provided with a plurality of the aforementioned second light-transmitting holes 221, and the second light-transmitting holes 221 can also penetrate the pixel definition layer 222 on opposite sides close to and away from the black matrix 212, and be coaxially arranged with the first light-transmitting hole 211, so that external light can be emitted into the accommodating space 400 through the first light-transmitting hole 211 and the second light-transmitting hole 221 in sequence, so as to be received by the photosensitive module 300.

[0038] Optionally, the material of the pixel definition layer 222 may be a negative adhesive, and under the influence of the negative adhesive properties, when the pixel definition layer 222 is exposed and developed to form the second light-transmitting hole 221, the aperture of the second light-transmitting hole 221 in the direction of the pixel definition layer 222 away from the black matrix 212 may gradually increase, so that the second light-transmitting hole 221 may be arranged in a trapezoidal hole. In this way, the second light-transmitting hole 221 may be formed with a larger opening on the side of the pixel definition layer 222 away from the black matrix 212 to expand the field of view of the first display area 201 toward the photosensitive module 300, that is, to expand the angle range of the light emitted from the second light-transmitting hole 221, so that the photosensitive module 300 can receive a wider range of light, so as to improve the light sensing accuracy and sensitivity of the photosensitive module 300. Of course, according to different design requirements, the material of the pixel definition layer 222 may not be limited to the negative adhesive, and the second light-transmitting hole 221 may not be limited to a trapezoidal hole. For example, the material of the pixel definition layer array 222 may also be a positive resin, and the second light-transmitting hole 221 may also be a rectangular hole or an elliptical hole, which is not limited in this embodiment.

[0039] The second refractive film 240 is disposed in the second light-transmitting hole 221, and the second refractive film 240 is used to diffuse the light entering the second light-transmitting hole 221 when it is emitted in a direction away from the first light-transmitting hole 211, so as to expand the angle range of the light emitted from the second light-transmitting hole 221 (equivalent to expanding the viewing angle of the first display area 201 toward the side of the photosensitive module 300), so that the photosensitive module 300 can receive a wider range of light, thereby improving the light sensing accuracy and sensitivity of the photosensitive module 300. Figure 6 As shown, the shape of the second refractive film 240 can match the second light-transmitting hole 221, that is, the cross section of the second refractive film 240 can also be set in a trapezoidal shape. At the same time, in order to enhance the diffusion effect of light, the refractive index of the second refractive film 240 in the direction of the black matrix 212 close to the pixel definition layer 222 can be gradually reduced, so that the light ( Figure 6 When passing through the second refractive film 240, the light (indicated by the dotted line L with an arrow) can be away from the axial center of the second light-transmitting hole 221 at a larger angle, so as to expand the angle range of the light emitted from the second light-transmitting hole 221. In this embodiment, the thickness of the second refractive film 240 can also be 100nm-1000nm, specifically 100nm, 400nm, 500nm, 800nm ​​or 1000nm.

[0040] Optionally, the refractive index of the second refractive film 240 can be linearly decreasing or nonlinearly decreasing. It is only necessary that the refractive index of the second refractive film 240 in the direction of the black matrix 212 close to the pixel definition layer 222 can be reduced so that the light can be away from the axial center of the second light-transmitting hole 221 during the transmission process. This embodiment is not limited to this.

[0041] Exemplarily, the second refractive film 240 may have multiple layers of second refractive layers 241, and the multiple layers of second refractive layers 241 may be stacked in sequence in the direction where the black matrix 212 is close to the pixel definition layer 222. The refractive index of the multiple layers of second refractive layers 241 in the direction where the black matrix 212 is close to the pixel definition layer 222 may gradually decrease, and the light may be refracted at a large angle when entering the second refractive layer 241 with the highest refractive index, and then transmitted by the multiple layers of second refractive layers 241 with successively decreasing refractive indices, so as to reduce the proportion of the light being refracted again during the transmission process, so that the light is emitted from the second light-transmitting hole 221 at a relatively large tilt angle, so as to expand the angle range of the light emitted from the second light-transmitting hole 221. In this embodiment, the material of the second refractive layer 241 may be an organic polymer or an inorganic silicon, and the number of the second refractive layers 241 may be 3-6 layers, specifically 3 layers, 4 layers, 5 layers or 6 layers.

[0042] For example, when the material of the second refractive layer 241 is an organic polymer, the multilayer second refractive layer 241 may be composed of a polymer material having one substituent group and multiple substituent groups. Among them, the refractive index of the second refractive layer 241 composed of the polymer material having multiple substituent groups may be greater than the second refractive layer 241 composed of the polymer part material having one substituent group. That is, the refractive index of the second refractive layer 241 composed of the polymer material with more substituent groups is greater, and the refractive index of the second refractive layer 241 composed of the polymer material with fewer substituent groups is smaller. Based on this, the number of substituent groups in the multilayer second refractive layer 241 in the direction where the black matrix 212 is close to the pixel definition layer 222 can be gradually reduced, so that the refractive index of the multilayer second refractive layer 241 in the direction where the black matrix 212 is close to the pixel definition layer 222 can be gradually reduced. In this embodiment, the number of substituent groups can be controlled by the process temperature, and the higher the process temperature, the more substituent groups in the second refractive layer 241, and vice versa.

[0043] The refractive index of the multi-layer second refractive layer 241 may vary in the range of 1.4 to 1.9. Among them, the refractive index of the top layer of the multi-layer second refractive layer 241 far from the pixel light emitting layer 220 is 1.9, and the refractive index of the bottom layer close to the pixel light emitting layer 220 is 1.4. For example, when the number of the second refractive layer 241 is 6 layers, the refractive indexes of the 6 layers of the second refractive layer 241 in the direction of the black matrix 212 close to the pixel definition layer 222 are 1.9 (SiNx), 1.8 (SiNx), 1.7 (SiNx), 1.6 (SiCN), 1.5 (SiNO) and 1.4 (HMDSO), and the thickness of the bottom layer far from the black matrix 212 among the 6 layers of the second refractive layer 241 is the largest (close to 500nm), while the thickness of the other 5 layers of the second refractive layer 241 is relatively thin. With such arrangement, the six second refractive layers 241 can allow light to enter the accommodating space 400 from the second light-transmitting hole 221 at a relatively large angle, so that the photosensitive module 300 can receive light in a wider range, thereby improving the light sensing accuracy and sensitivity of the photosensitive module 300.

[0044] Optionally, the number of the aforementioned multi-layer second refractive layers 241, the range of refractive index variation, and the selected materials can also be adaptively adjusted according to design requirements. It is only necessary that the refractive index of the multi-layer second refractive layers 241 in the direction close to the pixel light-emitting layer 220 can be gradually reduced, so that the light entering the second light-transmitting hole 221 can be away from the axial center of the second light-transmitting hole 221 and can be emitted from the second light-transmitting hole 221 at a relatively large angle. This embodiment is not limited to this.

[0045] Optionally, the light emitting layer 223 may include: a device layer 2232 and an anode layer 2233 ( Figure 4 ). At the same time, the pixel light-emitting layer 220 may also include: a cathode layer 224 located between the pixel definition layer 222 and the black matrix 212, and the cathode layer 224 may also cover the accommodating hole 2221, and be stacked with the device layer 2232 to cooperate with the anode layer 2233 to realize the light emission of the device layer 2232. In this embodiment, a plurality of light-emitting layers 223 and a plurality of filters 213 can cooperate to form a plurality of pixels, and a plurality of light-emitting layers 223 and a plurality of filters 213 can be arranged in a preset manner, such as a standard RGB arrangement, a Delta arrangement, and a Pentile arrangement, to form a pixel array. Among them, the specific light-emitting principle of the light-emitting layer 223 can refer to the prior art, which will not be described in detail here. Of course, the specific stacked structure of the light-emitting layer 223 may not be limited to such a setting, and this embodiment does not limit this.

[0046] See also Figures 7 and 8 , Figure 7 yes Figure 3 Another partial cross-sectional structural diagram of the first display area 201 along V-V, Figure 8 yes Figure 3 FIG. 2 is a schematic diagram of another partial cross-sectional structure of the first display area 201 along line V-V.

[0047] Exemplarily, the display panel 200 may further include: a driving circuit layer 250 and a base layer 260. Figure 7 As shown, the driving circuit layer 250 is stacked with the pixel definition layer 222 and is located on the side of the pixel definition layer 222 away from the black matrix 212, and the driving circuit layer 250 is also electrically connected to the light-emitting layer 223 to control the single light-emitting layer 223 to emit light independently. The base layer 260 is stacked with the driving circuit layer 250 and is located on the side of the driving circuit layer 250 away from the pixel definition layer 222, and the base layer 260 can be used to carry the driving circuit layer 250, the pixel light-emitting layer 220 and the color filter layer 210.

[0048] Further, the driving circuit layer 250 may specifically be a TFT thin film transistor array substrate, and the driving circuit layer 250 may include: an isolation layer 251, a buffer layer 252, a first insulating layer 253, a first dielectric layer 254, a second insulating layer 255, a second dielectric layer 256, and a planar layer 257, which are sequentially stacked. The isolation layer 251 is stacked with the base layer 260, and the planar layer 257 is stacked with the pixel definition layer 222 and is located on a side of the pixel definition layer 222 away from the black matrix 212.

[0049] Furthermore, the driving circuit layer 250 may also include: an active layer 250a, a gate layer 250b and a source-drain layer 250c. The active layer 250a may be disposed between the buffer layer 252 and the first insulating layer 253, the gate layer 250b may be disposed between the first insulating layer 253 and the first dielectric layer 254, and the source-drain layer 250c may be disposed between the second insulating layer 255 and the second dielectric layer 256. At the same time, the source-drain layer 250c may also be electrically connected to the active layer 250a through a via hole passing through the second insulating layer 255, the first dielectric layer 254 and the first insulating layer 253, and the anode 2233 may also be electrically connected to the source-drain layer 250c through a via hole passing through the flat layer 257 and the second dielectric layer 256, so as to realize the electrical connection between the driving circuit layer 250 and the light-emitting layer 223.

[0050] Optionally, considering the light transmittance problem of the first display area 201, the active layer 250a, the gate layer 250b and the source and drain layer 250c of the driving circuit layer 250 in the area within the first display area 201 can be integrated into the area within the driving circuit layer 250 within the second display area 202, so that the driving circuit layer 250 only has the aforementioned isolation layer 251, buffer layer 252, first insulating layer 253, first dielectric layer 254, second insulating layer 255, second dielectric layer 256 and flat layer 257 in the first display area 201, so as to improve the light transmittance of the partial area of ​​the driving circuit layer 250 located in the first display area 201, thereby increasing the amount of light that the photosensitive module 300 can receive.

[0051] Optionally, in addition to the above embodiments, the driving circuit layer 250 may also be provided with through holes penetrating the isolation layer 251, the buffer layer 252, the first insulating layer 253, the first dielectric layer 254, the second insulating layer 255, the second dielectric layer 256 and the flat layer 257 to transmit the light emitted from the second light-transmitting hole 221, so as to improve the light transmittance of the driving circuit layer 250. At the same time, in order to allow the light to enter the accommodation space 400 from the through hole at a relatively large tilt angle, a refractive film layer that is the same as or similar to the second refractive film 240 may be provided in the through hole provided in the driving circuit layer 250, so that the light can be diffused in a tilted direction away from the axial center of the through hole when transmitting in the through hole, thereby expanding the angle range of the light emitted from the through hole.

[0052] It can be understood that the aforementioned stacked structure of the driving circuit layer 250 is only an exemplary description, and the stacked structure of the driving circuit layer 250 can also be adaptively adjusted according to design requirements (such as increasing, decreasing or changing position, etc.). It only needs the driving circuit layer 250 to control the light-emitting layer 223 to emit light, and this embodiment does not limit this.

[0053] The base layer 260 may be a transparent base made of glass, quartz or PI (Polyimide) to ensure that the first display area 201 has sufficient light transmittance. At the same time, the base layer 260 may also be a flexible base or a rigid base, and may be adaptively selected according to the design requirements of the display panel 200, which is not limited in this embodiment.

[0054] Exemplarily, the display panel 200 may further include: an encapsulation layer 270, a touch layer 280, and a protective layer 290. Figure 8As shown, the encapsulation layer 270 is located between the color filter layer 210 and the pixel light-emitting layer 220, the touch layer 280 is located on the side of the encapsulation layer 270 away from the pixel light-emitting layer 220, and the protective layer 290 is located on the side of the color filter layer 210 away from the encapsulation layer 270. Among them, the encapsulation layer 270 can be used to encapsulate the pixel light-emitting layer 220 to reduce the probability of the pixel light-emitting layer 220 being corroded by water vapor. The touch layer 280 can be used to realize the touch function of the display panel 200, so that the user can click or swipe on the display panel 200 to realize the interaction between the user and the electronic device 10. The protective layer 290 can be used to protect the color filter layer 210 and the laminated structure on the side of the color filter layer 210 away from the protective layer 290, and the protective layer 290 can be a single layer or a multi-layer structure. For example, the protective layer 290 may include: a transparent adhesive layer 291 (OC glue), a cover layer 292 (UTG glass), and a barrier layer 293 (PET film) stacked in sequence in a direction away from the color filter layer 210. Of course, the stacked structure of the protective layer 290 may not be limited thereto, and this embodiment does not limit this.

[0055] The photosensitive module 300 can be arranged in the accommodating space 400 and located on the side of the pixel light-emitting layer 220 away from the color filter layer 210, and the photosensitive module 300 can receive the light emitted from the second light-transmitting hole 221 into the accommodating space 400 to realize the fingerprint recognition or ambient light detection function. In this embodiment, the photosensitive module 300 can be fixed on the middle frame 110 and arranged opposite to the first display area 201. Of course, the photosensitive module 300 is not limited to being arranged on the middle frame 110. For example, the photosensitive module 300 can also be integrated into the display panel 200, and the photosensitive module 300 only needs to be able to receive the light emitted from the second light-transmitting hole 221, and this embodiment is not limited to this.

[0056] The display panel 200 provided in the present application is provided with a first light-transmitting hole 211 and a second light-transmitting hole 221 respectively on the color filter layer 210 and the pixel light-emitting layer 220, and a first refractive film 230 for converging light is arranged in the first light-transmitting hole 211, and a second refractive film 240 for diffusing light is arranged in the second light-transmitting hole 221, so that the light passing through the first light-transmitting hole 211 and the second light-transmitting hole 221 in sequence can be first converged and then diffused. In this way, the display panel 200 can use the first refractive film 230 to converge the light incident into the first light-transmitting hole 211, and play a partial collimation effect on the light, so as to increase the light transmittance of the display panel 200. At the same time, the display panel 200 can also use the second refractive film 240 to diffuse the light emitted from the second light-transmitting hole 221, so as to increase the viewing angle of the display panel 200 on the side of the pixel light-emitting layer 220, so that the photosensitive module 300 can receive a wider range of light, thereby improving the photosensitivity and sensitivity of the photosensitive module 300.

[0057] Please combine Figure 4 See also Fig. 9 , Fig. 9 yes Figure 3 Schematic diagram of the partial cross-sectional structure of the first display area 201 and the second display area 202 along V-V.

[0058] like Figure 4 and Fig. 9 As shown, when external light enters the display panel 200, a certain proportion of the light will be reflected at the light-emitting layer 223 and emitted from the display panel 200, and the main reflection area of ​​the light-emitting layer 223 includes: a portion of the cathode layer 224 arranged opposite to the pixel hole 2121, and an anode layer 2233 exposed on the side of the pixel definition layer 222 facing the black matrix 212 through the receiving hole 2221. Among them, since the portion of the cathode layer 224 corresponding to the pixel hole 2121 is not blocked by the black matrix 212, and the cathode layer 224 is made of a metal material with a high reflectivity, the surface reflectivity of the cathode layer 224 corresponding to the pixel hole 2121 can generally reach 25-40%. At the same time, since the anode layer 2233 is also made of a metal material and has a higher reflectivity than the cathode layer 224, the surface reflectivity of the anode layer 2233 exposed on the side of the pixel definition layer 222 facing the black matrix 212 through the receiving hole 2221 can generally reach 95%.

[0059] Furthermore, when the black matrix 212 is provided with the first light-transmitting hole 211 in the first display area 201, the area of ​​the cathode layer 224 corresponding to the first light-transmitting hole 211 is not blocked by the black matrix 212, so a certain proportion of light will also be reflected when it is incident from the first light-transmitting hole 211 to the cathode layer 224, so that the light reflectivity of the first display area 201 is increased compared with that of the second display area 202, thereby causing a difference in visual effects between the first display area 201 and the second display area 202. Based on this, in order to reduce the difference in light reflectivity between the first display area 201 and the second display area 202, the light reflectivity of the light-emitting layer 223 located in the first display area 201 in this embodiment can also be lower than the light reflectivity of the light-emitting layer 223 located in the second display area 202, so as to offset the part of the light reflectivity of the first display area 201 that is increased due to the opening of the first light-transmitting hole 211, thereby reducing the difference in visual effects between the first display area 201 and the second display area 202.

[0060] Exemplarily, the black matrix 212 can be divided into a first pixel area 212a and a second pixel area 212b according to the first display area 201 and the second display area 202, and the black matrix 212 can be provided with a plurality of first light-transmitting holes 211 in the first pixel area 212a. Meanwhile, the pixel holes 2121 can also be divided into a plurality of first pixel holes 2121a and a plurality of second pixel holes 2121b according to the first display area 201 and the second display area 202, and the first pixel holes 2121a are provided in the first pixel area 212a, and the second pixel holes 2121b are provided in the second pixel area 212b. In addition, both the first pixel holes 2121a and the second pixel holes 2121b can be used to arrange the filter 213.

[0061] The light-emitting layer 223 can also be divided into a plurality of first light-emitting layers 223a and a plurality of second light-emitting layers 223b according to the first display area 201 and the second display area 202, and the orthographic projection of the first light-emitting layer 223a on the black matrix 212 is located in the first pixel area 212a, and the orthographic projection of the second light-emitting layer 223b on the black matrix 212 is located in the second pixel area 212b. At the same time, the first light-emitting layer 223a may include: a first device layer 2232a and a first anode layer 2233a, and the second light-emitting layer 223b may include: a second device layer 2232b and a second anode layer 2233b. Among them, the arrangement of the cathode layer 224, the first device layer 2232a and the first anode layer 2233a, and the second device layer 2232b and the second anode layer 2233b is the same or similar to the cathode layer 224, the device layer 2232 and the anode layer 2233 in the aforementioned embodiment, and will not be repeated here.

[0062] The receiving hole 2221 can also be divided into a plurality of first receiving holes 2221a and a plurality of second receiving holes 2221b according to the first display area 201 and the second display area 202, and the first receiving hole 2221a is also coaxially arranged with the first pixel hole 2121a, and the second receiving hole 2221b is also coaxially arranged with the second pixel hole 2121b. At the same time, the number of the first light-emitting layer 223a and the first receiving hole 2221a is the same, and a single first light-emitting layer 223a is located in a single first receiving hole 2221a. The number of the second light-emitting layer 223b and the second receiving hole 2221b is the same, and a single second light-emitting layer 223b is located in a single second receiving hole 2221b.

[0063] In this embodiment, when external light enters the first display area 201 and the second display area 202 of the display panel 200, the light reflectivity of the first light emitting layer 223a is lower than the light reflectivity of the second light emitting layer 223b, so as to offset the light reflectivity of the first pixel area 212a increased by the first light-transmitting hole 211, thereby reducing the difference in visual effects between the first display area 201 and the second display area 202. The solution in which the light reflectivity of the first light emitting layer 223a is lower than the light reflectivity of the second light emitting layer 223b is further described below.

[0064] Exemplarily, the opening aperture of the first accommodating hole 2221a on the side close to the filter 213 may be smaller than the opening aperture of the second accommodating hole 2221b on the side close to the filter 213, so that the surface area of ​​the first anode layer 2233a exposed on the side of the pixel definition layer 222 close to the black matrix 212 is smaller than the surface area of ​​the second anode layer 2233b exposed on the side of the pixel definition layer 222 close to the black matrix 212, so as to reduce the light reflectivity of the first anode layer 2233a, thereby offsetting the partial light reflectivity increase of the first pixel area 212a due to the opening of the first light-transmitting hole 211, thereby achieving the purpose of reducing the difference in light reflectivity between the first display area 201 and the second display area 202. In this embodiment, the difference between the opening diameter of the first accommodating hole 2221a on the side close to the filter 213 and the opening diameter of the second accommodating hole 2221b on the side close to the filter 213 can be 0.4-0.6μm, specifically 0.4μm, 0.5μm or 0.6μm, so that the surface area of ​​the first anode layer 2233a can be reduced by about 2-12% compared with the second anode layer 2233b, so as to reduce the light reflectivity of the first anode layer 2233a.

[0065] Exemplarily, the opening aperture of the first pixel hole 2121a on the side close to the first accommodating hole 2221a can be smaller than the opening aperture of the second pixel hole 2121b on the side close to the second accommodating hole 2221b, so that the surface area of ​​the cathode layer 224 corresponding to the first pixel hole 2121a is smaller than the surface area of ​​the cathode layer 224 corresponding to the second pixel hole 2121b, so as to reduce the light reflectivity of the cathode layer 224 at the first pixel hole 2121a, thereby offsetting the part of the light reflectivity increased in the first pixel area 212a due to the opening of the first light-transmitting hole 211, thereby achieving the purpose of reducing the difference in light reflectivity between the first display area 201 and the second display area 202. In this embodiment, the difference between the opening aperture of the first pixel hole 2121a on the side close to the first accommodating hole 2221a and the opening aperture of the second pixel hole 2121b on the side close to the second accommodating hole 2221b is 1-6μm, specifically 1μm, 3μm, 4μm or 6μm, so that there is no obvious difference in brightness and chromaticity between the first light-emitting layer 223a and the second light-emitting layer 223b under the light output viewing angle.

[0066] Optionally, the aperture difference between the first accommodating hole 2221a and the second accommodating hole 2221b, and the aperture difference between the first pixel hole 2121a and the second pixel hole 2121b may not be limited thereto, and the specific difference between the two may also be adaptively adjusted according to the actual design requirements of the display panel 200, which is not limited in this embodiment.

[0067] For example, when the black matrix 212 uses a positive glue and the pixel definition layer 222 uses a negative glue, the apertures of the first pixel hole 2121a and the second pixel hole 2121b in the direction of the black matrix 212 close to the pixel definition layer 222 can be gradually reduced, and the apertures of the first receiving hole 2221a and the second receiving hole 2221b in the direction of the black matrix 212 close to the pixel definition layer 222 can be gradually increased. At this time, the first anode layer 2233a will have a first edge region C1 whose orthographic projection overlaps with the pixel definition layer 222, and the second anode layer 2233b will have a second edge region C2 whose orthographic projection overlaps with the pixel definition layer 222. Among them, since the OD (optical density) value of the pixel definition layer 222 is generally around 0.5-2, the overall light shielding degree is not good, and the area where the pixel definition layer 222 overlaps with the first edge area C1 and the second edge area C2 is a taper angle (about 20-30°) transition area (thin thickness), the pixel definition layer 222 cannot completely block the first edge area C1 and the second edge area C2, so that the first edge area C1 and the second edge area C2 will also reflect a certain proportion of light.

[0068] Based on this, in order to reduce the difference in light reflectivity between the first display area 201 and the second display area 202, the orthographic projection area of ​​the first border area C1 on the pixel definition layer 222 can also be smaller than the orthographic projection area of ​​the second border area C2 on the pixel definition layer 222, so as to reduce the reflection surface area of ​​the first border area C1, thereby offsetting the increase in part of the light reflectivity of the first pixel area 212a due to the opening of the first light-transmitting hole 211, and achieving the purpose of reducing the difference in light reflectivity between the first display area 201 and the second display area 202. In this embodiment, the orthographic projection areas of the first border area C1 and the second border area C2 on the pixel definition layer 222 can be controlled in the process, such as increasing the exposure, etc., which will not be described in detail in this embodiment.

[0069] The display panel 200 provided in the present application is provided with a color filter layer 210 having a first pixel region 212a and a second pixel region 212b, and the color filter layer 210 is provided with a first light-transmitting hole 211 in the first pixel region 212a, so that the first pixel region 212a can use the first light-transmitting hole 211 to improve its own light transmittance. At the same time, by providing a pixel light-emitting layer 220 including a first light-emitting layer 223a and a second light-emitting layer 223b, and the orthographic projections of the first light-emitting layer 223a and the second light-emitting layer 223b are respectively located in the first pixel region 212a and the second pixel region 212b, and the light reflectivity of the first light-emitting layer 223a is lower than the light reflectivity of the second light-emitting layer 223b, so that the light reflectivity of the first pixel region 212a increased due to the first light-transmitting hole 211, which causes the pixel light-emitting layer 220 to be exposed, can be substantially offset, so as to reduce the difference in visual effects between the first pixel region 212a and the second pixel region 212b.

[0070] The above descriptions are only some embodiments of the present application, and do not limit the protection scope of the present application.
